Precise and Accurate mean the same thing. I would consider measuring more than once to get a precise or accurate measurement.
In Ni(CO)₄ the stoichiometry of Ni to C is 1:4
for every 4 atoms of C is attached to one Ni atom.
this means that if there are 4 atoms of C - 1 atom of Ni
in 5.23 x 10²⁴ atoms of C -1/4 x 5.23 x 10²⁴ atoms of Ni
= 1.3075 x 10²⁴ atoms of Ni
the number of atoms rounded off to the second decimal place = 1.31 x 10²⁴ atoms
correct answer is E
There are 4 types of orbitals. The s, p, d and f orbitals. They can contain a maximum of 2, 6, 10 and 14 electrons, respectively. So, for the 1s energy level, you would expect a maximum of 2 electrons. That includes elements 1 and 2, hydrogen and helium. <em>These are the only 2 elements in the first period.</em>
By gaining an electron (perhaps via beta particle). The H+ ion needs another electron to remove its positive charge.
Answer:
False
Explanation:
The uptake and the release of the oxygen in the hemoglobin is monitored by a effect known as <u>cooperative effect</u>. It states hat when one oxygen molecules i being added to one of the four heme units of the hemoglobin, there will be some structural changes in the heme which further facilitates the uptake of the oxygen for the second heme and thus further facilities for the other two heme units with much greater rates.
<u>This is same with the release of oxygen from one unit of the hemoglobin which further facilitates the removal of the oxygen from other units. Hence, the given statement is false.</u>
